mod_http_file_share: Remove correct entries when not all expired files were deleted If any of the expired files could not be deleted then we should not forget about that, we should complain loudly and try again. The code got this backwards and would have removed only the entries referring to still existing files. Test procedure: 1. Upload a file 2. chown root:root http_file_share/ 3. In uploads.list, decrease 'when' enough to ensure expiry 4. Reload mod_http_file_share 5. Should see an error in the logs about failure to delete the file 6. Should see that the metadata in uploads.list is still there 7. chown http_file_share/ back to the previous owner 8. Reload mod_http_file_share 9. Should see logs about successful removal of expired file 10. Should see that the metadata in uploads.list is gone 11. Should see that the file was deleted
